您好,我给您一个范例吧,比说什么都强基于BP神经网络的管理类期刊影响因子的影响因素分析李宁(陕西科技大学学报编辑部 陕西 西安 710021)LI Ning (Editorial Board of Journal of Shaanxi University of Science and Technology; Xi'an 710021; China);【摘要】采用神经网络方法建立了评估期刊影响因子与相关影响因素之间非线性对应关系的分析模型,模型以刊期、总被引频次、即年指标、载文量、被引半衰期、引用半衰期、他引比、基金论文比、Web即年下载率等为网络的输入,以影响因子作为网络的输出,根据中国期刊综合引证报告提供的数据进行了网络训练和测试。分析表明,影响因子受刊期影响最大,受他引比、载文量影响较大,受基金论文比、即年指标影响较小,而与Web即年下载率几乎无关。[关键词]影响因子 影响因素【英文摘要】Based on neural network,the paper establishes analysis model about the nonlinear relationship between journal impact factor and related indexes in the process of The model uses journals publication frequency,the total cited frequency,immediacy index et al as the inputs,and takes impact factor as the Using the datum of Chinese Academic Journals Comprehensive Citation Report,it also does the network training and The results show that impact factor is influenced the greatest by ratio
